From one of the worlds most celebrated and bestselling novelists comes an epic adventure in the spirit and tradition of Monsoon and Blue Horizon. It is 1884, and in the Sudan, decades of brutal misgovernment by the ruling Egyptian Khedive in Cairo precipitates a bloody rebellion and Holy War. The charismatic new religious leader, the Mahdi or Expected One, has gathered his forces of Arab warlords in preparation for a siege on the city of Khartoum. The British are forced to intervene to protect their national interests and to attempt to rescue the hundreds of British subjects stranded in the city. Along with hundreds of others, British trader and businessman Ryder Courtney is trapped in the capital city of Khartoum under the orders of the infamously iron-willed General Charles George Gordon.
